Figure 11 is a fragmentary horizontal sectional view of the casing.

In the drawings 10 designates an open casing having a raised boss 12 including an opening 13 and merging into a clutch bear ing flange 14. The casing 10 is also provided with a lower bearing 15 and outside bearing plate 177 embodying upper and lower bearings 17 and 16 respectively.

The casing 10 embodies side walls 18 and 19 having oppositely disposed lower surface flanges 20 and 21. Extending vertically in said walls18 and 19 is a pair of slots 22 and 23 respectively out of registration. Upon the vertical edges of said slots is a pair of extending flanges 24 and 25 projecting inwardly into the hollow interior of the casing for a purpose which will be hereinafter disclosed. Disposed adjacent the lower edges of the vertical slots 22 and 23, and secured to the opposite walls 18 and 19, are the stamp guide plates 26 and 27, each of said plates being provided with a stamp receiving shoulder 29 preferably in the same horizontal plane.

Associated with one end of the casing 10 is a water reservoir 30 comprising a substantially closed body embodying an inclined wall 31 having a closure 32 adapted to receive a threaded cap 133. T he reservoir 30 is made in two parts, for instance, the rear wall 33 is secured to the inclined and front wall 31, and the bottom of the reservoir casing is overlappecL and secured together in any well known manner. The rear wall 33 is provided with an opening 34, and secured adjacent thereto on the inside of the rear wall 33 is the framing element 35 adapted to receive a yieldable flat element 57 which may be of rubber or the like to form a resilient closed wall which bears snugly against the sides of opening 84, being air and liquid tight. 7

The reservoir 30 is suspended within the open casing 10 and is supported by the outwardly extending flange 36 suitably mounted on a plate 3? and by the spring rel'lexed portion 38 snugly fitting the inclined shoulder 39 of the reservoir casing.

Adjacent the bottoinof the reservoir casing 30 is a plurality of horizontal extending tubes. 40 (one being illustrated in Figures 1, 2, and 7) although in actual practice one or more may be employed. These tubes project beyond the reservoir wall, and have a longitudinal bore 41 of minute diameter, forming a water seal for the liquid within the reservoir casing to preclude the discharge of any liquid through the tubes except through pressure exerted on the liquid or upon the air above the head of the liquid.

The plate 37 is suitably and detachably secured to the upper edges of walls 18 and 19 in any well known manner. The plate 37 is provided with a collar 42 having the complemental bearing flange 43 which provides a supporting means for the outwardly extending flange 36 of the rear wall of the reservoircasing 30. Extending vertically of the casing 10 and slidably associated within the upper bearing plate collar 42 is the plunger 44 having a stem 45 and embodying a contracted threaded terminal 46 adapted to receive the stud plate 47 which carries the guide bracket plate 48. Suitably affixed to the stud plate 47 is a fiat resilient mat 49 having a plurality of corrugations 50 on its lower face to obviate a vacuum in supplying air in the corrugated spaces to prevent suction between the lower mat face and the stamp to be affixed.

The upper portion of the plunger 44 is provided with a knob 51 having a boss 52 at the upper end thereof. Interposed between the upper bearing collar 42 and the boss 52 of the knob is a resilient coiled spring 53 which is adapted to hold normally the plunger in elevated position. Depending from the outwardly extending flange 36 (see Figure 7 is the irregular shaped leaf spring 54 having a recessed portion 55, an abutment raised portion 66 and a cup shaped terminal 56 adapted to loosely engage in normal position the flexible yieldable flat element 57 The stem 45 is provided with a saddle 58 having a pair of freely extending arms 59 and 60 between which is journalled the fulcrum pin 61 and on the latter is rotatably secured the trigger 62. The saddle 58 is adjustably mounted on the stem 45 of the plunger by means of the set screw 90.

The trigger comprises a body having an upper bearing face 63 and a pair of lower engaging cam surfaces 64 and 65 for engaging with the recessed portion 55 and the raised portion 66 on the leaf spring 54. A leaf tension spring 67 is secured to the under face of the trigger 62 at one end and the other end bears loosely against the surface of the stem 45. In the raised position of the plunger, the cam portions 64 and 65 of the trigger bear loosely against the recessed portion 55 and the raised portion 66 of the leaf spring 54. On the downward movement of the plunger 44, it will be apparent that the trigger surface 68 abuts the surface of stem 45 and forces the cam face 64 of the trigger against the raised face 66 of the leaf spring element thefstem45 against a shoulder 69 and emarm of the bell crank lever. 'Th-e shou bodies a flat horizontal lower plate indicated by reference character 48 and a standard (see Figures 4 and 8) having the lateral lug 71 provided with an extension embodying shoulders see Fi ure 8 adaated to abut the a: l l l n flanges 24 of the opening 22 in too wall 10. The flanges 24 ad acent the opening of slot 29 form'a guiding means for the contracted extension on the lateral lug 71 of thestandard.

The standard 70 is provided with abell crank lever 72 (see Figure 9) which is lulcruined on the pin 73' secured to the standard 70 which embodies an otl set stop member The bell crank lever 72 comprisesa long a 111 7 5 and a short arm 76 and the latter is pro vided with a perforation 77 andthe longer arn is provided, at its terminal, with an operating pin 78. The longer arm of the bell crank lever embodies the flat face also indicat-ed by reference character 72, hearing against the outer. face of standardTOand t 1e remaining portion of the long arm is oil-set and extends away from the engaging lace'ot' the standard 70 as clearly 'llustrated in t Figure 4. i l i i The operating pin 78 ext-ends laterally from the loweroil-set portion. of thelon r or on the standard 70 forms an abutinentlior the off-set part ofthe long arm 7 A coiled spring 80 is passed through the perforation 77 of the short arm 76 and is secured there to while the other end of the coiled spring 80 is secured to the oil-set guiding lug71 inany suitable manner. The coil spring 80 normally maintains the oil-set longarin oithe bell crank lever in engagement with the shoulder 74 of the standard 70.

Suitably mounted on the guide bracket plate 48 is a spring 81 (Figure 10), rigidly set about'the stem 45, embodying a pair-oi end loop shaped spaced ears 2 and 83 and the latter merge into a pair of interconnected spaced cutter operatingfingers 84 The loops are interconnected by-the integral brace 85 (see Figure 10). ltis to be understood that the springSl is a single integral inember which is shaped to comprise the loops 82 and 83, the interconnected brace '85 and the spaced cutter operating fingers 84. The fingers actuate the cutter 97 and straddle the standard92 (see Figure 1).

Integrally associated with said 1 guide bracket plate 48 is a projecting arm 86" having the lateral extension 87 embodying a cont-racted terminal portion 88 provided with suitable shoulders 89 which bear against the sides of the frame flanges 25 contiguous to the vertically disposed slot 23 in the casing wall '19. 1

'It will be appreciated that upon the clownward stroke otthe plunger the extensions 71 and 87 of the guide bracket plate 48 are guided in their path of travel by the pairsof flanges 24 and 25 respectively. Disposed between the open sides of the casing 18 and 19 and fixedly secured therebetween is the cutter standard bearing frame 101 embodying the contracted stainp discharge slot 91 and the intergral elevated cutter support92 which is suitably provided with an opening 93 extending longitudinally thereof.

The upper portion 01 the standard is pro videdwith a lug 94 having a perforation in l which is secured one end of the coiled spring 95 while the other end of the spring is lined to the lateral enter 1011 96 0i the cutter 97.

The flange 96 registers with'and is slidably gu ded by the lower opening 93 of the stand The cutter comprises the flat plate 97 having its terminal portions guided by one flange 2 (see Figure 11} and snugly bears against the standard support98v(see Figure 2) by means of apair of tensionsprings 99 suitably and thestandard walls 98. Gt course, the

lived as at 100 on the upper edges of the stamp ltuwill be seen that the tension 7 cutter 97 "is provided with a sharp, sloping,

bevelled edge 103. Normally spring 95 maintains the cutter 97 in elevated posit1on above the opening 91. i l a c i The open casing 10 is provided with a detachable cover comprising the 'arcuate closure 104 whichis suitablyhinged at 105 and is locked to the chute niount 106 at 107 by any well known means. a The locking means may comprise the conventional lock and key elements to preclude unauthorized use of the stamps on the supply roll 108'1nounted within the casing. The chute inountltls is secured between the walls 18 and 19 and against the frame standard support 101. Thefree por tion of the ar'cuate cover is detachably=se-,

cured to the upper bearing plate 87 by a spring lock comprising a pair of intercon nectedeleinents 109 and 110 one 01 whichex tends downwardly from the upper bearing plate and the other is reflexed upwardly about the free end of the arcuate closure 104,

and coacts with the depending extending portion 109.

Preferably mounted within the opening 13 of the casing 10, (see Figure is the indeX- 1 ing, timing and spacing mechanism, and the same comprises (see Figure'3) a stud screw 111 comprising a circular bearing face 112 and a rectangular contracted shoulder 113 having a terminal threaded portion 114. The upper face of the stud screw is provided with a recess 115 and a central threaded opening 116. A feed gear 117 embodying the ratchet 118 which is suitably fixed thereto by pins 119 (see Figure 5) is mounted upon the stud screw 111. The gear 117 is provided with a circular recess 120 in which is mounted the metallic washer 121 rotatable in the recess 120.

The washer is provided with an aperture 122 in which is detachably secured the lock synchronizing screw 123 and the latter registers with and operates within an arcuate slot 124, and securely locks the washer to the casing boss Adjustably secured within the recess 115 on the stud screw is the timing, indexing, locking and spacing cam 125, by means of the set screw 126.

The lock metal washer 121 is provided with an elon ated central opening 127 which regsters and reacts with the stud shoulder 113. The lock nut 124 is threaded on to the terminal portion 114 and holds the washer 121 against the edges of opening 13 and also se- 1 cures the washer within the recess 120 of the gear 117. Mounted within the recess 115 of the stud screw 111 is the timing, indexing, lockin g and spacing cam 125 by the extension 528 which is locked in the recess 115 by the screw 126.

In other words, the stud screw 111 is mounted within the opening 13 and carries the metal syncln'onizing washer 121 fitting within the recess 120 of the gear 117. The outer end of the stud screw 111 adjustably retains the lock nut 124 which firmly secures in nonrotatable position in the opening'13 the stud screw 111 and the set screw 123 locks the washer to the side of casing 12. It will be than that the gear and the ratchet are roably secured on the central bearing of the 1d screw and the cam 125 is fixedly secured within the top face 115 of the stud screw. 'To change the position of the cam 125 all that is necessary, is to release the synchronizing loci: screw and lock nut 124 from the side wall 12 and rotate the washer 121 either one way or another within the limits of the arcuate slot 124 and securing the lock screw 5:23 and lock nut 124 against the wall 12 when proper ichronizing adjustment is obtained. 'lllr" one lock screw 123 is utilized to obn 15. 11 the proper timing relation of the cutter 7 with the feeding mechanism for severing the stamps along the lines of their perforations of the stamp roll.

The ratchet 118 is provided with a plurality of curved hooks 128 and a plurality of diagonally disposed notches 129 each notch being so positioned as to be contiguous to a hook.

The timing, indexing and spacing cam em bodies the irregular shaped plate 125 having a perforated extension 128. The cam embodies also an arcuate off-set integral indexing finger 130 having an index spring prong 131 which coacts in springing engagement, with either of the notches 129 in the ratchet causing a click which constitutes an audible signal that the stamp feed is complete before knife or cutter 97 is ready to cut.

The earn 125 embodies an areuate cam face 32 merging into a tapering deflecting nose 33. The washer 121 is p ovided with a shoulder 134 (Figure bearing against the sides of the opening 13 and adjustably secured therein (see Figure 5). When. the audible signal is heard the pin 78 is knocked off the ratchet hook 128 by cam surface 132 and follows edge of deflecting guide 133.

The stamp supply roll 108 is preferably mounted on a metallic tube 135 and is rotatably secured on the shaft 136 extending between the casing walls 18 and 19 and is slidably locked therein in the inclined recesses 137. The stamps .areprefcrablymounted on the tube 135 to reduce the binding action with the surface of the shaft 136 and to aid with the least possible friction, the stamp dispensing discharge from the stamp roll.

For guiding a continuous supply discharge of stamps severed at their proper parallel disposed perforations, there is provided a novel chute mounted in the cutting standard hearing frame 101 and the chute mounting comprises a casing 138 secured in the cutting standard'bearing frame 101 which embodies the diagonally d sposed inclined guiding plates 139 and 140.

Cooperating with the feed gear 117 are the upper and lower stamp feed guiding rolls 141 and 152, respectively. The upper feed roll ismounted on a shaft 143 extending transversely the width of the casing and the roll 141 is provided with a plurality of spaced circumferential grooves 144, also shaft 143 is rotatably secured in the outside bearing plate 177 and the bearing 14 of the casing 10. The shaft 143 is further provided with complemental interacting clutch elements 145 and 146 provided with cooperating serrations or teeth 147. The clutch element 146 is provided with a manual manipulator 148 and an abutment 149 through which the pin fastened to shaft 143 is fixed and adjacent the serrations of the clutch element 146 is a coiled spring bearing against the collar abutment 149 surrounding the shaft 143 and also bears against the flange 150 norm ally locking the clutch element 146 on the complement clutch collar 145 which is loosely mounted on the shaft 148 and rotatably within the bearing 14. Apinion 151 is fiXedl carried by thecomplemental collar 145. and engages with. the feed gear 117 of the timing, spacing and indexing mechanism. I r

Secured to the lower shaft 142. which: is suitably journalled in aligned bearings and 16 on the casing and provided with the necessary play in the lower stamp guiding roll 152 (Figure 2). embodyingthe longitudinal groove 153 and a plurality oflo'sely disposed and spaced collars 154, 155,156 and 157.

mThe shaft 142 is provided adjacent the bearing 15 with an'enlarged boss 158 acting as an abutment against the shoulder of hear ing 15 and cooperating witha circumferential flange 159 which forms an abutment for purposes which will be hereinafter set forth; The intermediate collar 155 is provided with a. recess adapted to receive a leaf spring160 preferablysecured to the inclined faceof the arcuatedetachableclosure '104. l I i The leatspring, 160 normally rests in the recess 180 of the intermediatecollar 155 and keeps the lower roll in proper operating position. It will be noted that the collars 154, 155 and 156. are provided with circumferential grooves 161 adapted to receivelower chute constituting wires. 1 162 1 (see Figure 1).. 1 The wires 162 extend inthe directionof 1 inclined lower chute plate 140 andterminate with their freeends turnedslightly upward ly ior keeping the stamp flat, when discharged frorn the opening 91. The upper feed roll is also provided with supplemental stamp T guiding means inthe form of spaced Wires 163 extending at an incline in spaced juxtaposed, relation to the .lower'set of: wires .162

and alsohave their ireeendsterminate with their free ends turned upwardly adj acent the discharge opening 91.' 1 y i The upper and lower seriesof spaced wires i are suitably secured in spaced relationship to the inclined plates 139 and 140 respectively. The upper ends of the series of wires .163 are turned 'over'the upper roll 141 and reflexed within the grooves 144. The upper terminals 0151116 lowerjs'eries of wires 162 are reflexed withinthe groovesil'tilpn the spaced collars.

It will he seen that. the jg'ap provided he: tweenthe upper and lower series 'ofwires forms a downwardly sloping passageway having the proper spacing to eliminate bucklingofthe stamp strip in its travel through i inequalities in the width of thestamp due to variations in temperature humidity and other natural incidents; proper adj ustment the chute to opening 91 andYafter-dis'charge. the stamp is in aflat horizontal plane.

. To compensate 'for' the irregularities and maybe had whereby the stamps of irregular width register ;with their perforated line alwaysin shearing position'under the cutter.

By varying the acting. gfeed circumference on the lower roll, for example where 'thereis a variation, from the standard width of the 1 stamp through the reduction'or increase in the width of the stamp, the actual cutting adjustment would have to be synchronized in such way withithe feeding action ofthe stamp ing yieldable and resilient washers 164 in an"- nulus formation. disposed between the collar 1 154 and the circumferential .flange 159 befeed rolls to allow for this reduction or increase, and this is. accomplished by vprovidtween the adjacentcollars l54 and 155; be-

1 1 5 I terminal collar 157 willc ause theyieldable annular members 164 to. give, thereby inf collars in moving the threaded stem 171 away from the pin 166. The inherent resilience of the yieldable members 164 will tend to spread the collars apart when the stem 171 moves away from the pin 166.

The stamps from the supply roll 108 are threaded between the upper and lower rolls '141 and 152 and between the unbuckling guide wires 162 and 163 to the discharge mouth 91 and fed on to the stamp guide plates 26 and 27 which support the stamp in a horizontal plane on the shoulders 29.

, Where it is required to affix a stamp to an envelope surface, the machine is placed bodily on the envelope so that the stamp affixing area is substantially between the lower bearing flanges 20 and 21 between the walls 18 and 19 of the casing 10.

In the operation of the device,'four functions take place on the downward stroke of the plunger 44, to wit :first, the moistening; second, the feeding; third, the severing or cutting; fourth, stamping. That is to say, when the plunger is depressed, the first operation occurs when the trigger surface 68 abuts the stem 45, trigger 62 actuating the leaf spring 54 causing the yieldable diaphragm 57 to be distended thereby increasing the pressure within the liquid container 30 dispensing jets of liquid through the nozzles 40 onto the affixing surface of the envelope (not shown) which is placed between the spaced stamp guideplates 26 and 27. As the plunger moves downwardly, pin 78 of the bell crank lever 72, comes in contact with one of the aligned hooks 128 of the ratchet 118 and causes the ratchet to rotate the gear 117.

Because of the engagement of the pin 78 with one of the hooks 128, locking point 131 of the spring finger 130 is released from one of the notches in the ratchet 118. The release of the spring finger from the notch allows the gear to rotate until the pin arrives at the knocked off position. That is, the

pin in its downward travel against the ratchet is also in riding engagement with the cam surface 132 of the cam 125 and it is at the merger of the deflecting plate guide 133 with the cam surface 132 that this knocked off position takes place.

When the pin has reached the knocked off position, it will be seen that the ratchet has caused the gear to move one part of a revolution and consequently the spring finger 130 is move d'into a new notch locking the ratchet. The gear 117 transmits motion to the gear 151 of the loosely mounted clutch collar 145 and accordingly rotating the upper feed roll on shaft 143 one revolution and the latter actuates the lower feeding roll on the shaft 142 one revolution causing the stamps from the supply roll 108 to be led between the unbuckling guide wires 162 and 163 and to the orifice 91 ready to be severed by the downwardly progressing knife or cutter 97 which has been actuated by the spring fingers 84 of spring 81.

In the severing position of the stamps, the feed rolls and the cutter automatically cooperate, that is, the severing takes place along the line of the perforations. A stamp, after being severed, is held on the shoulders 29 of the guide stamp plates 26 and 27 and is maintained in asingle plane because of the unbuckling action previously referred to of the guide wires 162 and 163 in the guide chute 139 and 140 and the reflexed terminals of the guide wires adjacent opening 91. In the final part of the plunger stroke, the stamp becomes alfixed to the envelope surface by the action of the plate or mat 49 on the press plate 47 acting upon a stamp as it is held between the shoulders 29. Between the knocked off position on the cam 125 and the vanishing point on the deflecting guide plate 133, the cutting or severance of the stamp and the affixing occurs. Following the alfixing of the stamp. the plunger moves upwardly and the pin 78 moves along the deflecting plate upwardly and directly over a ratchet hook but in spaced relation therewith, so that upon the next downward stroke of the plunger 44, the pin 7 8 will engage the aligned and adjacent ratchet hook 128.

Of course, normally the cutter 97 is held in uncutting position" by the spring 95 and the normal position of pin 78 is in alignment with one of the hooks of the ratchet by reason of the spring 80. i

V For controlling the synchronization of the cutter with the feeding means either in advanced or retarded position the adjusting synchronizing screw '123 is loosened so that the washer 121 may be rotated either one way or another within the gear recess and the arcuate casing slot 124.

In practice, it isgenerally advisable, first to thread the supply stamp roll and strip of stamps between the upper and lower stamp feed rolls; then downwardly through the chute 139 and 140 until the aligned perforations of a pair of stamps are flush with the wallj98 or directly under the cutter and subsequently releasingthe clutch by detaching thecoupling 146 from the clutch collar 145 thereby disengaging the clutch collar 145 and gear 151 from the shaft 143; and finally rotating the manual manipulator 148 causing the pin 245 to actuate shaft 143, consequently rotating the upperfeed' roll and the latter actuates the lower feed roll.

When one revolution of the manipulator has been completed the proper stamp width should have been fed into position for severance along the line of perforations. If not, the lower collarsare adjustedin suchmanner as heretofore explained so that the yieldable-washers 164 will either be increased or decreasedin'diameter for proper widthdischarge ofa' stamp along the line of perforations under the severing position of the cutin connection with theaccompanying drawings, it is believed that several novel, structural features of my present improvement as Well as the advantages thereof in practical operation will be readily appreciated. Because of the simple form of the various elements entering into the disclosed construc tion the device may be produced at comparatively small manufacturing costs.

- I have also described and illustrated in the accompanying drawings a structural. embodiment of the device which I have found to give highly satisfactory results, and it will. be obvious to those skilled in the art after an understanding of my invention, that other changes and modifications may be made without departing from the spiritand scope of my invention, and I aim in the appended claims to cover such changes and modifications as arewithin the scope of my invention.
